applied and the link coupled. Fig. 2 is alongitudinal Vsection of thedraw-head, showing the coupling-pin raised.' Fig. 3 is a bottom .view ofthe draw-head.

A represents the car iitted in the usual way with a draw-bar, B, havinga draw-head, C, D being the ordinary pinfand E the couplinglink. Thedraw-head is bell-mouthed and ymade of considerable depth, so as topresent a large opening tothe free end of 'the couplinglink of a caradvancing to be coupled, and facilitate a sure entry. The throat ofthedrawhead only affords sufficient room for the link to lie in it snuglywhen coupled, and is continued into the draw-bar to accommodate asliding block, F, which is adapted to be set forward by means of one ofa pair of levers, F', one of which is placed on each side of the car,and are pivoted to the block F by means of a pin, f, projecting througha slot, b, in the unf der side of the draw-bar.

rear ofthe car, and provided at each end with a lever-arm, l1, and inthe center with a downwardly-bent arm, which is suitably connected by achain, 7L', or otherwise to the lug g of the frame G. A chain or otherconnection, I, may also be employed to operate the arm H from the roofof the' car.

My improved coupling operates as follows: The link is raised by pullingdown one of the arms 7L orA pulling np the chain I,therehy raising theframe G and the pin D. The blockF is now moved forward by means of oneof the 'levers F', and the under-cut end of the block will pass underthemend of the pin D and carry' the same, as shown in Fig. 2. A link, E,entering the mouth of the draw-head,will strike against the end of theblock F and push it back,thereby removing thersupport of the pin D,which will instantly drop into the link and secure it. `I am aware ofPatents Nos. 162,336, 218,466, and 267 ,531, and I do not broadly claimasliding block, F, the levers F', guide-frame G, nor rocking shaft H; but

I claim as my invention- 1 "Ihe combination of the throated drawbar B,Wide-mouthed draw-head C, couplingpin D, sliding-block F, levers F',frame G, rocking shaft H H', connected with the frame G.

2. In a car-coupling, a slidinglblock, F, in combination with pinf, fastin said block, slot b in the draw-head, through which said pin j'projects, and levers F, pivoted to said pin. y

3. The combination of the rocking shaft H, lever-arms 71.,downwardly-bent arm H, chain 71,', lug g, bolt d, pin D, and guide-frameG.
